On the subject of Moggies - anybody know why mine has a tendency
to 'run on' for a few seconds after the ignition has been switched
off? Somebody told me it was to do with the unleaded fuel - she's
originally a leaded engine that the Morris Minor Centre in Bristol
'unlead-ised' with the aid of a 'magic' thingy that fits in line with
the fuel - apparently they've been fitting them for 20 years..

Oh dear. That 'magic thingy' does precisely nothing - lucky you didn't pay
for it.

Unless the exhaust valve seats have been modified to incorporate hardened
inserts you're in for problems sooner or later if running on unleaded only.
The A Series engine is one of the worst around for valve problems with
unleaded unless modified. But don't worry - it won't actually break down
totally so you can wait until it shows symptoms before doing anything. A
sensible choice would be to have a modified cylinder head standing by.

As regards the running on many fit an electrically operated valve
connected to the inlet manifold after the carb which opens and lets in air
when you switch off. But you should first check the ignition isn't
retarded and that the mixture isn't too weak - either can cause running on.
